AI Technical Summary
Existing technologies for monitoring surface erosion in sand-covered hilly areas struggle to accurately identify the spatial shifts in erosion zones when the directions of wind and water erosion are inconsistent. This leads to inaccurate assessments of the distribution of concentrated erosion areas and affects the reliability of early warning systems.
By acquiring wind field variables, water field variables, and surface state variables, a surface particle migration field and an initial runoff path field are constructed. Combined with a multi-field coupling model, the spatial migration distribution of erosion is calculated, and erosion areas under the action of wind and water erosion are identified.
It has enabled accurate positioning of the spatial displacement area of erosion in sand-covered hilly areas, improving the accuracy of erosion risk area identification and the reliability of early warning.
